[Cost of illness of age-related macular degeneration. Systematic review on the development of a costs diary].

Due to demographic changes in the German population a significant rise in incident cases of age-related macular degeneration (AMD) is to be expected in the coming years. Also the corresponding increase in costs of the illness requires appropriate survey instruments to allow accurate estimations of costs. The cost diary for patients with AMD developed in this study is based on a previously established systematic review. The seven studies that were included were evaluated regarding their quality in order to then extract the listed cost items. The result is a prospective survey instrument with six different cost sectors of AMD.
